If a subcontractor calls 811 on Friday afternoon, don't schedule Monday's excavation from elapsed hours alone. California's ordinary notice period excludes the notification date and counts working days. Before releasing the crew, check the ticket's legal start time and the responses from the listed operators.
California's ordinary 811 notice requirement is two working days or more before excavation, excluding the notification date. The arrival of the ticket's legal start time does not remove the separate requirement for the listed operators to fulfill their response obligations.
Keep the ticket with the excavation assignment so the foreman can compare it with the work area. 29 CFR 1926.651(b) supplies the federal underground-installation framework. California's more specific notice provisions need to be read on their own terms.
Start with the California provisions
Government Code §4216.2(b) calls for ordinary advance notice of two working days or more and no more than fourteen calendar days before excavation. It expressly excludes the date of notification from the two-working-day notice. The section also addresses emergency work and agreements for a different notice and start date. Those provisions should not be reduced to an undocumented override in a permit form.
Cal/OSHA 8 CCR §1541(b)(2) separately calls for advance advice to the relevant notification centers and known owners of subsurface facilities that are not members. Its language specifies two working days or more before digging, with an emergency exception. A completed one-call ticket therefore does not establish that every separate obligation to a known nonmember owner has been met.
The federal text at 29 CFR 1926.651(b)(1) requires the estimated locations of reasonably anticipated underground installations to be determined before opening an excavation. Paragraph (b)(2) addresses contact and response times. Apply these federal precautions alongside California's notice requirements.
What working day means for the legal start time
Government Code §4216(v) defines working day for determining the legal excavation start date and time. It includes Monday through Friday, from 7 a.m. to 5 p.m., with the specified federal and state holiday exclusions and the regional center's posted information. The state-holiday reference is §19853. Do not replace it with any holiday list that happens to appear in a payroll application.
Keep the statutory hours in the scheduling procedure. If the company's calendar counts every Monday through Friday as a full working day, document how the notification center's posted dates and hours will be checked before that calendar is used for excavation planning.
Neither §4216(v) nor §4216.2 supplies a complete written algorithm for every after-hours call and observed-holiday edge case. Confirm how the appropriate regional center has set the legal start date and time on the ticket. Preserve that value rather than silently replacing it with the result of a local spreadsheet.
When reviewing the release, retain the applicable state timing alongside the contact record needed by 29 CFR 1926.651(b)(2). The foreman needs both pieces of information when an operator has not yet responded.
Separate an example calendar from authorization
Consider a hypothetical request made on an ordinary Monday, with no intervening excluded holiday. Monday is the notification date and does not count as either working day. Tuesday and Wednesday are the following two working days. The legal start date and time actually assigned to the ticket still needs to be checked before work is released.
Now change the facts. One of those weekdays is an excluded holiday, the request describes the wrong work area, or the ticket lists an operator whose needed response has not arrived. The Monday example no longer supplies the answer. On a training calendar, mark the notification date separately from the two working days. Then compare the result with the legal start date and time recorded on the ticket.
Avoid scheduling language such as “call Monday, dig Wednesday” without qualifications. Workers may remember the slogan after forgetting the holiday and response checks. Under 29 CFR 1926.651(b)(2), the relevant contact and location duties remain tied to the actual excavation. A date printed on a whiteboard cannot identify a utility.
Check responses before releasing excavation
Government Code §4216.2(g)(1) addresses commencement: unless an emergency exists, excavation cannot begin until the listed operators have fulfilled the specified obligations and any needed onsite meeting has been completed. Paragraph (g)(2) describes circumstances in which excavation can begin before the legal start date and time. Treat this as a defined statutory provision to verify, not permission to assume silence means clearance.
Assign someone to review the responses for each operator listed on the ticket. Record who checked, when and what remained unresolved. If a response refers to plans, markings or an onsite meeting, the foreman needs those items at the work location. An email saying “the ticket is in the system” is not a response review.
Federal 29 CFR 1926.651(b)(3) separately calls for the exact location to be determined by safe and acceptable means as work approaches the estimated location. A marked line establishes information to use; it does not remove that approach-stage duty. Our excavation safety guide places utility precautions alongside cave-in, access and atmosphere requirements.
Match the ticket to the work the crew will perform
A ticket for an earlier phase may not describe the trench now being opened. Compare the location, excavation limits, planned activity and the excavator's information against the actual assignment. Resolve mismatches through the appropriate center process before treating the ticket as evidence for that work.
Consider a hypothetical project that first excavates a short service connection and later extends a trench around the building. A ticket number entered on both work permits does not establish that the second area was included. The supervisor should be able to show the relevant description and responses rather than relying on the fact that the project has an active number.
The field review supports the estimated-location duty in 29 CFR 1926.651(b)(1). It also prepares the crew for the protective measures required while utilities are exposed under 29 CFR 1926.651(b)(4). Keep the ticket's administrative status and the condition of an exposed installation as two separate checks.
Manage the twenty-eight day ticket period
Government Code §4216.2(e) gives the ticket a twenty-eight day period from issuance and calls for renewal by the end of the twenty-eighth day when work continues. Paragraph (i) addresses a ticket that expires while work is ongoing: excavation needs to cease, a new ticket needs to be obtained and the commencement conditions need to be satisfied before resuming.
Schedule a review early enough to handle continued work through the needed process. An internal reminder is a recommendation, not another legal notice period. Keep the issuance, renewal and expiration information together so a replacement supervisor can tell which ticket governs today's excavation.
This date control does not replace inspections. Federal 29 CFR 1926.651(k)(1) addresses competent-person excavation inspections, including before work and after hazard-increasing events when employee exposure is anticipated. The competent-person designation guide explains the authority and capability behind that role. A valid ticket can coexist with an excavation that is unsafe to enter.
Build a release record that can be checked at the trench
The following record layout is an EHS management recommendation. It is not a claim that California mandates this particular form.
| Check | Evidence to keep with the excavation assignment |
|---|---|
| Work matches the request | Ticket description and current excavation limits |
| Notice timing checked | Notification record and the center's legal start date and time |
| Operator duties addressed | Responses for each listed operator and needed meeting record |
| Known nonmember owners considered | Contact details and location information where applicable |
| Ticket remains current | Issuance and renewal records |
| Field precautions ready | Approach method, protection of exposed installations and assigned responsibility |
Link this record to the crew's job hazard analysis. Use the JHA Builder to organize task steps and controls, then add the actual ticket references. The tool does not determine whether the statutory commencement conditions have been met.
Under 29 CFR 1926.651(b)(4), exposed installations need to be protected, supported or removed as needed to safeguard employees. The field precautions row should therefore name the expected condition and the person who will address it. “811 complete” provides too little information for that decision.
Keep the permit handoff connected to field authority
Decide who can withhold release when a ticket, response or marking is inconsistent with the work. The foreman should know how to reach that person before the excavator arrives. A schedule change should trigger a review of the ticket conditions rather than automatic acceptance of a new start time.
When work resumes after a delay, recheck the conditions that may have changed. Under 29 CFR 1926.651(b), utility location and protection remain operative duties throughout the relevant stages of excavation. Under 29 CFR 1926.651(k), the competent person's inspection remains a separate protection against excavation hazards.
The Friday request in the opening example should reach Monday's pre-task meeting with its actual ticket, responses and unresolved items. If those records do not support release, the crew needs a revised assignment or a hold decision before equipment breaks ground.
Frequently Asked Questions
Is California's 811 waiting period simply forty-eight hours?
No. Government Code §4216.2(b) calls for two working days or more and excludes the notification date. Section 4216(v) defines working day for determining the legal excavation start date and time. Use the actual ticket and applicable center information.
Can digging start as soon as the legal start time arrives?
Time alone is insufficient. Government Code §4216.2(g) also calls for the listed operators to fulfill their applicable response duties and any needed onsite meeting to be completed. Cal/OSHA 8 CCR §1541 adds excavation safety obligations.
How long is a California excavation ticket valid?
Government Code §4216.2(e) states twenty-eight days from issuance and calls for renewal by the end of the twenty-eighth day if work continues. Paragraph (i) addresses an expired ticket while work is ongoing. Check the ticket's scope and current status as well as its date.
Does federal OSHA provide California's two working day calculation?
No. 29 CFR 1926.651(b) establishes federal underground-installation duties, including contact within applicable response times. California's notice and ticket provisions come from Government Code §4216 and following sections and 8 CCR §1541.
